I Application filed October 27, 1914. Serial No. 868,849.

To all whom it may concern:

Be it known that I, SAMUEL E. Vnsnnn, a citizen of the United States, and resident of Chicago, in the county of Cook and State of Illinois have invented certain new and useful Improvements in Charging and De livering Mechanism for Cone'Baking Machines, ot which the following is a specification.

'Bhe present invention relates to machines for molding articles from plastic material and baking such articles. the class of articles for which the herein illustrated embodiment of the invention is particularly intended being pastry cones, known commonly as ice cream cones. and the particular type of machine to which this invention is applied being generally that shown in. my pending application filed January 2, 1914, Serial Number 810,063 for machine for baking pastry cones.

The features to which the present invention particularly relate are a filling or charging mechanism for the mold or molds of the machine, and an improved means for removing the baked, or otherwise finished articles, from a mold or molds.

I desire to state that in characterizing the invention as above, I have not intended to limit the particular invention hereinafter described and claimed to a machine of the specific nature disclosed in my prior appli- Iation aforesaid, but I consider that the invention is applicable to machines and apparatus for producing other sorts of articles, and intend the folltnving claims to einbrace all charging and delivering mechanisms having the characteristics recited in the claims, whatever may be the purposes to which they may be devoted. ,In the following description of the hereinafter illustrated embodiment of my invention, 1 shall refer to my prior application No. 810,063 for the purpose. of illustration and to assist in giving a clear understanding of the mode of operation of this particular embodiment, but without any intention of limiting the invention otherwise than the same limited by the express terms of the appended claims.

The objects of the present invention appear from the following description of the construction and operation of the herein illustrated ei'nbodiment of the same.

in the accompanying drawings, Figure 1 is a plan view of so much of a machine such n'ieans.

as that shown in my prior application above referred to, with the new features of the present invention applied thereto, as is necessary to illustrate this invention. Fig. 2 is an elevation of that part of the machine shown 1n Fig. 1,with the charging or filling apparatus removed. Fig. 3 is an elevation representing that part of the machine shown. 1n Fig. 1 as viewed from the opposite side of Fig. 1 from the View shown in Fig. 2. Fig. l

Fig. 6 1s an elevation and partial section of the mechanism shown in Fig. 5 as seen from the right of said figure. Fig. 7 is a plan view same parts in all the figures.

It is to be understood that the ba" machine to which the appliances embonyi my present invention are applied consists of av turntable 1 (Fig. 3) having outwardly t projecting arms 2, each of'which carries a mold, or molding unit. The turntable rotates about a. column 3, bemg driven by a pawl and ratchet mechanism in substantially the manner explained in my prior application referred to. The ratchet is designated 4; in the present drawings, and is rigidly secured to the turntable. The pawl is designated 5 and is in the form of a. sliding bolt carried by an arm 6, which projects from a sleeve 7 rotatable about the column 3 and is driven by a crank pin 8 on a disk 9 through a connecting rod 10. The crank disk 9 is on a shaft 11, which may be driven by means such as shown in my application before referred to, or by any other desired The pawl 5 is pressed toward the rim of the ratchet disk by a spring 12, as shown in Fig. 1 so that it may enter notches 13 in such rim, the pawl and notches being beveled on one side and being square on the other so that the mechanism is positive in one direction and the pawl is adapted to withdraw from the notches on the reverse strokes. A holding pawl 14 is mounted on a fixed holder 15 and pressed toward the disk by a spring 16 to prevent reverse movement of the turntable. A cam 17 is mounted on the shaft 11 and is provided with a cam groove 18, which actson a stud 19 on a connecting rod 20 to reciprocate the latter for purposes hereinafter described. Rod

20 is forked at one end as shown at 21 to embrace the shaft 11, whereby said rod is K tation of the turntable through an oven, of

which the outlet end is shown in a fragmentary way in Fig. 1 and is designated 26, and the molds are opened and closed at stated times by means such as shown in my prior application or by any other suitable means. The intermittent movement given to the turntable by the pawl and ratchet drive causes the turntable to stop just after each mold emerges from the oven and also just before each mold enters the oven, and while the mold is in position to be filled. The filling or charging device forms a fea- I ture of the present invention and will now be described. Such device is mounted upon a fixed post 27 which rises from a suitable base outside of the sweep of the mold carryingarms. To the upper end of such post there is fixed a bracket28 having divergent horizontal arms 29 and guides 30 on the ends of said arms. The bracket 28 also has upstanding lugs 31 between which is pivoted a rocker 32. The guides 30 receive guide rods 33 of a structure which-may be called for the purposes of this invention a pump carrier, and which consists of the said rods 33, and a yoke or cross piece 34 lifter rods 35 pass through the yoke 34 and have heads 36 overlying said yoke, and are secured to the batter chest 40, later described. The yoke is provided with lugs 37 to which is pivoted one end of a connecting link 38, the other end of said link being pivoted to the rocker 32. Oscillation of the rocker, by means presently to be described, causes the pump carrier to move up and down, the rods 33 then sliding in the guides 30.

The charging device, or pump, is mounted upon the pump carrier and consists of one or more pump units, equal in number to the mold-cavities in the molding unit.

In the present instance there are seven mold cavitiesi'h -each molding unit, and a like number of pump units. The barrels of .these pump units are designated 39 and are all connected with achest 40, which contains the batter, or other plastic material, used by the machine. Each pump barrel has a port 41 communicating with the chest 40, as shown in Fig.6, and the latter is provided with inlet couplings 42 at one or both ends for connection with a reservoir or other larger supply of batter, whereby 'it may be constantly replenished. Preferably the reservoir is set far enough away from the baking machine to avoid liability of the batter being heated and dried by the heat from the machine, thus avoiding one source of waste. A pump or. any other. suitable means maintains a circulation of the batter from the.

main supply tank through the chest or chamber 40 and back to the tank, supplying as much batter as is needed to make the full charge of each of the pumps, but without supplying too much batter. The pump barrels and chest, which are preferably made inone piece, may be called the casing structure of the pump. This casing structure is secured to the rods 35 at the'lower ends of the latter, and thereby suspended from the pump carrier. This casing structure also carries one or more adjustable stop screws 43 passing freely through eyes in lugs 44, which are fixed to the arms of bracket 29. The screws 43 have heads 45 and lock nuts 46 on respectively opposite sides of the lugs44, which act as 'abutments to limit the possible reciprocating movement of the pump casing structure, and one "of these abutments is adjustable. The lower ends of the pump barrels are provided with outlet nozzles 47 which register with the openings to the corresponding cavities of the molding unit which is in charging position. The pump plungers are shown at 48 and are secured to the yoke 34 of the pump carrier, passing through such yoke and having adjustable securing nuts 49 and 50 above and below the yoke, respectively. The plungers reciprocate with, and also relatively to, the pump barrels, to an exact amount regulated by the adjustment of the nuts 49 and 50 and of the abutments 44 and 46. In the upper limit of their travel relatively to the barrels, the plungers uncover the ports 41, as indicated in Fig. 6.

Each pump contains a valve in the outlet passage leading from its here. such valve being conveniently a plug cock 51 having a passage 52 adapted to be turned into and out of registry with the outlet passage of the pump, as shown in Fig. 9. Each of these cocks has an arm 53, and. all of such arms are connected by a bar 54. In addition the cock of each of the two endmost pump units has an arm 55 at the end opposite to that on which the arm 53 is mounted, and these arms 55 are connected together by a bar 56. The connecting bar 5% car ries'a stud 57 over which extends a latch or pawl 58 having a shoulder 59. This latch is supported by a link 60 which is pivoted to a stud 61-on the pump casing structure and has in its sw1nging portion a slot 62 receiving both pivotally and slidingly a stud 63 which forms the connection between this link'and the latch. A spring 6 1 is connected to the studs 61 and 63 and tends to hold stud 63 at the inner limit of the slot 62. A bell crank lever 65 is also pivoted on the pump casing structure on a pivot stud 66. One arm of this bell crank, which is shorter than the link 60, is connected by a pivot 67 with the latch 58 and the other arm is connected by a pivot 68 with a link 69, the latter being pivoted on a stud 70 projecting from an arm 71 fixed on one of the pump plungers 1-8. The bar 56 which connects the arms on the otherends of the ump cocks carries a shoulder or abutment 12 in the path of an arm or finger 73, which projects froma rocking element 74. This element 7% is a sleeve pivotally supported on a stud 75, which is suspended from the bracket 28, being connected to a cross piece 76, which passes between the arms of said bracket, as shown in Fig. l. The rocking sleevehas an arm 77 connected by a link or connecting rod 78 with an arm 79 on a sleeve 80 which is oscillatively mounted on the post 27 and is confined between the bracket 28 and a collar 81, which is clamped to the post by a set screw 82.

I will now describe the mechanism which operates the pump and the cooks to cause the batterito be injected into the mold at the proper times.

The connecting rod or link 20 previously described is joined 'to an arm 83 on a rock shaft 84, which is properly supported in bearings at the foot of the column 27., This rock shaft carries a second arm 85 with which the lower end of a. link or connecting rod 86 is attached by means of a pivot stud 87, which is adjustable in a slot 88 of the arm 85. The upper end of link 86 is connected to the rocker 32; hence when the rock shaft Sal is oscillated the rocker is likewiseoscillated and the pump is moved up and down. The first operation in charging is a downward movement of the pump, caused by the offset part of the cam 18 moving the connecting rod 20. which movement istran'smittcd through the connecting rod 86, and rocker to the pump carrier. In the first part of this movement the plungcrsAB force the casing structure downward until the stops l5 strike the fixed abutment lugs 44, when the casing structure is arrested. The carrier yoke continues in motion, sliding along the lifter rods 35, and the guide rods 33 sliding through the guides 30, and advances the pump plungers 48 in the now sta tionary pump barrels 39, thus ejecting the batter. WVhile the plungers move thus relatively to the pump barrels, the bell crank 65 is oscillated by the connections thereto from one of the plungers, and the latch 58 is moved bodily causing its shoulder 59 to strike the stud.57 and move the bar 5%,thcreby shifting the pump cocks from the closed position shown in Fig. 9 to the open position. lVhen the cock has arrived in this popivot 63 of the latch more than the fulcrum pivot 67 is lowered, thereby swinging the latch about its connection 67 with the bell crank in the direction which causes its disengagc ment from the stud 57. Thereby the cocks cease to turn when they arrive in the open position, and the plungers are enabled to expel the batter during the remainder of their downward movement. subsequently closed by the finger 73, which strikes the abutment 72 on the connecting bar 56, and moves it in the direction opposite to the movement just described. The finger 73 is actuated to this effect after the plungers have ejected the batter and before the turntable has shiftedthe molding unit from the'filling position, by means of the driving pawl carrier 6 which, in its return stroke after advancing the turntable, strikes a 101189 on an arm 90, which projects from rnupright rock shaft 91 mounted in a hearing 92 near the central column of the machine. This rock shaft carries a second arm 93 connected to a link 94:, which is also connected by the pivot pin 95 with a lever 96 which has a hub 97 supported and rotatable freely'on the rock shaft 84. An arm 98 rises from the lever 96 and is jointed to an arm 99 which extends from the sleeve 80 previously described as carrying the arm 79. The connection between the arms 98 and 99 consists of a block 100 which is pivoted to a lug. 101 on the arm 99 and to which is pivoted an eyebolt 102, which passes through the arm 98 and is secured by a cotter pin 103. The pivots connecting the block 100 with the lug 101 and the cyebolt 102 are at right angles to each other, whereby the arms 98 and 99 are capable of swinging, without binding, in different planes. It is understood that the oseillation of the sleeve 80, imparted through the mechanism last described, moves the finger 73 through the arm 79, link 78, arm 77, and rock sleeve 74 to .give the desired [closing movement to the pum cocks.

The cocks are lets 104 thereof are closed by a cover 105, shown best in Fig. 7, which is mounted on one of the parts of the molding unit on studs 106 and is permitted to move between the limits imposed by the slots 107 which re ceive said studs, such limits be ng wide enough to permit the cover to be w1thdra-wn to one side of the mold inlets, and to be column.' A dog 113is pivoted on the pusher 109, or on the abutment plate 110, in the path of an actuator lever 114, which lever is pivoted by a stud 115011 a bracket 116 secured to the column 27. Dog 113 has a tail piece 117 which extends under a finger 118 projecting from the connecting rod 86 which actuates the rocker of the pump carrier. Actuator lever 114 has an arm 114 extending below its pivot and connected by a link 119 with an arm 120 which is fixed on the rock shaft 84. In the movement of the rock shaft which causes descent of the pump, the actuator 114 is moved outwardly and under the dog 113, raising such dog by contact of its .outer cam-like surface with the dog. When the actuator has passed under the dog the latter falls back by its own weight in the path of the actuator. On the reverse stroke of the pump, the actuator 114 is-moved inwardly and pushes against the dog 113, thereby forcing the pusher against the stud 108 of the cover 105 and closing the latter. This action occurs as soon as the pump begins to rise after the charge has been injected into the mold. As the pump continues to rise and the operating link 86 to descend, the finger 118 on said link bears on the tail' 117 of the dog and lifts the dog above the tip of actuator 114, whereby the pusher is released from the actuator and allowed to move outback again into position to make a working stroke when the pump is again operated as above described. The cover on each mold is withdrawn into the position shown in Figs. 6 and 7 upon emerging from the oven, by means of a cam 122 secured to the each molding unit cover as the same passes out of the oven;

I will now describe the new and improved means for receiving the finished product from the molding and baking machine.

Each mold as it emerges from the oven stops in the discharging position occupied by the arm 2 shown in Fig. 1. When in this position the ejector plate 124, which forms the bottom of the mold and may be constructed and arranged in the same manner as the ejector plate in my prior application referred to, is raised by a forked arm 125 which receives a roll 126, on a frame 127 which hangs from the ejector plate, The arm 125 is raised and lowered by the shaft 84 through an arm 128 on said shaft, a connect ing rod 129 extending from said arm, and an arm 130 on the rock shaft 131 which oscillates the actuator arm 125 through a link 132 and an arm 133, all substantially as described in my prior application. In Fig. 2 I have shown the ejector and elevating frame therefor and the actuating arm 125 in skeleton, having left out the other parts of the molding unit and the turntable arm by which the same are carried. It is to be understood, however, that in the actual machine the member 124 is arranged substantially as is the corresponding ejector in the machine shown in my prior application. The upward movement of the actuator arm 125 raises the ejector to the level of a stationary receiving table 134, which is supported upon posts 135 rising from the base of the machine, in a position close to one edge of the table and in a vertical plane extending between such edge and a cone transferrer 135 This transferrer has a number of pockets corresponding in shape and spacing to the shape and spacing ofthe finished cones or other articles, and is carried by a rod 136 which is secured to the arm 99 previously described as projecting from the sleeve 80 mounted on the post 27. In normal position the transferrer 135 is far enough removed from the edge of the receiving table 134 (see Fig. 1) to permit the baked cones carried by the ejector to pass between. such edge and the transferrer. \Vhen the arm 99 is moved as previously described,

. the transferrer sweeps across the ejector and the receiving table, and carries the cones before it, each of the pockets in the transferrer receiving and positioning one of the cones. Adjacent to and somewhat remow'edfrom the opposite edge 138 of the stationary table is a guide 139 corresponding in form and complemental to the transferrer 135 and having recesses adapted to receive the cones and spaced correspondingly thereto. The trans' ferrer sweeps the cones across the table and up against the guide 139 over the space between such guide and the edge 138 of the receiving table, and the cones drop through this space upon plugs 140 which rise from a rotatable depository. The depository here shown is a table 141 having a shank which is mounted rotatably in a bearing 14; carried by a bracket 143 which secured to the posts 135 of the receiving table. This depository has form-arms, each of which carries a setof plugs alined and spaced correspondingly to the pockets in the transferrer 135 and guide 139; and it is intermittently rotated and stoppec after each step of its rotation with one set of plugs directly under the cavities in the guide 13$). Thus the cones, or other baked articles, after having been swept across the receiving table by the transferrer and properly located by the eoaction of the transferrer with the guide, fall upon the plugs 140 and are received and positioned by them. The intermittent rotary movement mentioned is given to the cone depository by a pawl 144 upon an oscillating pawl carrier 145 co-acting with notches 146 in a rotating disk 147 secured to the shank of the deposi; tory. The pawl carrier is connected by a link 148 with a lever 149 pivoted at 150 to the bracket 143, and it carries an anti-friction roll 151 on its end nearthe receiving edge of the table 134 in position to be struck and displaced when the mold-carrying arm 2 is moved from the discharging position. The movement given to the lever 149 by the arm 2 displaces such lever in the direction required to give the pawl 144 its operative stroke,'and it continues 'far enough to move the pawlthrough the angular distance be tween two of the notches 146. A spring 152 returns the pawl carrier and lever 149 to their normal position after the arm has passed by the roll 151. A retaining pawl 153 holds the depository when the pawl moves back after its operative strokes.

It is to be understood that the receiving means for the baked cones is located adjacent to the stopping point of the molds immediately after emerging from the oven, and that the charging pump mechanism is located adjacent to another stopping position of the molds. These two positions may be proximately adjacent ones or not as desired.

The driving mechanisms for the' operations hereinbefore described are so arranged that these operat ons take place in sequence and without interfering with one another or with the movements ofithe mold-carrying turntable. The charging amreturn strokes of the pumps occur shortly after the turn table has come to rest after each step of its, intermittent movement. v the actuator for the cone ejector raises-the At the same time ejector With the baked cones from the mold which is in discharging position, .up to the level of the receiving table; and While the cone ejector is raised, the pawl carrier 6, which in the meantime has commenced and proceeded on its backward stroke from one of the notches 13 toward the next one, engages the roll 89 on arm 90 and swings said arm so as to swing the arm 1% with the transferer 135, in the manner already described, across the ejector and the de pository. During this swinging movementof the transferrer, the finger 73 is caused to close the cocks of the pump elements. Thereafter the pump plungers and pumps rise and a fresh charge of batter is drawn into the pumps, and the pawl carrier is given its next forward stroke to turn the turntable a further step, then permitting the arm 90 to return to normal position, to which. it is returned by the spring 160 shown in Fig. l, and thereby the transferrer 135 and the cock operating finger 73 are returned to their normal positions. The formation of the cam 18 and its position with respect to the crank pin 11 are so designed as to cause the steps described to take place in the proper sequence.

I desire to say in reference to the terms used in the foregoing description, that such terms are used descriptively in connection with the particular illustrated embodiment of the invention, and without limiting significance. These terms have been chosen in the effort to explain the particular form of the invention here shown in a clear and graphic manner. I wish it understood that I intend to include within the scope of these terms any mechanisms and parts which have the same essential. characteristics of construction and operation as the mechanisms and parts here shown, even though the most restricted definitions of terms here used should not include the same. Also it is to be understood that I do not limit the invention to any particular number of elements in the pump or of mold cavities in the molding unit, but include within the scope of the invention a charging device having only one pump unit as well as a machine having only a single mold.
